Why do the vast majority of these seem to either block off the 40pin header or convert it to female header that's incompatible with further hats? And why are they full sized, despite having minimal circuitry on them? I can appreciate the ones that build in a cooling system, but that doesn't need to block off all the pins that aren't being used by the hat.

It seems like all this could be accomplished with a small board that doesn't interfere with everything else one intends to do with a Pi or Pi-clone. In fact, I'm surprised at the lack of built-in POE Pi boards out there.

I need a few of these for rpi's around the farm. Tired of dealing with LoRa.

If I bring up things like mail or a post in a new tab, I have to go into Login/Manage Accounts and choose my account to do anything in that tab.

Terrible diagram 1

I'm trying to figure out how long to make A and B here if I have linear actuator of length C (extended = 2C) in order to tilt my panels from completely horizontal to vertical so they avoid wind and shed snow respectively when I run up the actuator to the extremes respectively based on sensor input.

Is there a simple formula I can use to plug the length of whatever actuator I settle on to figure A and B out? I know it will have to be a certain minimum and maximum size to work properly and might have to experiment to get an idea of what works in the end, but I'd like a reasonable start point to purchase an appropriate actuator.

I've googled around and decided I'm not smart enough to even come up with the right search criteria, let alone figure this out myself since it's been 35 years since I've used anything except the most basic trig.

This isn't really homework except for the fact that I'm trying to make my home work right.

Edit: seems like if I select A=.75C and solve for B at horizontal, then it always works out. No idea why, but the couple examples I try seem to agree.

I'm looking for a lowish priced laptop that I can put at least 2 extra monitors on. I want a second landscape 4k and a portrait 1080. Don't need anything special. One monitor has DP and HDMI, but the other just HDMI. Do I just get a DP hub and use a converter dongle for the second?

What would be a recommended laptop for this scenario? I only want AMD CPU and GPU as I can't be arsed to fight with noVideo and Intel doesn't deserve my business.

I have no idea how long this has been a thing, and maybe every clipboard works that way, not just Plasma, and I never realized it. It also lets you do things like Rt-click on it and do the regular operations like Search in Firefox. Spaces aren't preserved unless you specifically select them but search engines seem to be able to sort out the words usually.

I post this in case you haven't been part of the 10,000 this day already, like me.

Edit: seems to work in Firefox and LibreOffice, but not Kate or Okular. I'd love to see this as a general feature, it's handy as heck.

Looks expensive. The grey ones are the broken ones.

Thank you for the great work, Vernor. You'll be missed.

We have our house and a cabin. While I guess I could make an area for the cabin, it has it's own areas that I'd like to manage separately (and copy automations directly).

I have purchased a HA Cloud sub but I don't seem to be able to get the cabin to connect to Cloud.

Do I need a separate sub for the cabin at full price? This seems a little over the top, not to mention clunky to manage with different Nabu Casa logins.

Or am I just going about this wrong? If anyone else manages two properties and integrates it nicely, I'd love to hear your solutions. I'm mainly subbing to Cloud because of the better TTS and STT response. Maybe I just invest in a skookum whisper/piper box instead?

I don't see that there's any sort of integration for writing code to process information from HA entities like Node Red + Companion. Am I missing something and this is more than just an interface for the config files and maybe a git client for those config files?

These things aren't bad, I've got a few that I use sort of successfully, but the speaker and mic aren't very powerful. I was thinking of building one with an ESP32 and i2S (not i2c, that threw me off too) speaker/mic, but I'm wondering if I'd be reinventing the wheel here if there's a better alternative already out there.
